What is a tracking pixel?
1 min readAug 21, 2017
Tracking pixel technology allows services like Google Analytics to tell companies how many people have visited their site. In the world of digital display advertising, tracking pixels are used so that advertisers know how many people have seen their digital ad, or visited a website.
When users take a certain action — visiting a site, opening emails, viewing your digital ad, etc. — they send a request to the server to download the tracking pixel attached to the content they’re interacting with. It’s an invisible process to the user but the data collected can help brands build better digital ad and content experiences for consumers.
